MOTOR.

SPECIFICATION forming part of Letters Patent No. 361,937, dated April 26, 1887.

Application filed June 10, 1886. Serial No. 204,704. (No model.)

To all whom, it may concern:

Be it known that I, JAMEs GREGORY, acitizen of the United States, residing at Bogansville, in the county of Union and State of South Carolina, have invented certain new and useful Improvements in Mechanical Motors, of which the following is a full, clear, and exact description.

This invention isin the nature of a mechanro ical motor or power, so called, for driving machinery of various kinds; and the invention consists of a shaft carrying and operated by means of a revoluble medium, which latter is actuated through the shaft by levers, as I r 5 will now proceed to more particularly set forth and claim.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1. is a side elevation of one form of my invention, and Fig. 2 is a plan view of the same.

Upon a suitable frame-work, A, in proper boxes, a, secured thereon, is mounted a horizontal revoluble crank-shaft, b. In this in- 2 5 stance the shaft has two cranks, c, of opposite projection from the shaft. One end of this shaft is provided with a band-pulley, d, for transmitting the power to the machinery to be driven. Instead of transmitting the power 0 of the motor byv pulley and belt, gear-wheels or a crank may be employed. The other end of this shaft is provided with a fly-wheel (indicated by the broken circle 20, Fig. 2) or its equivalent, and as an equivalent, and having 3 5 superior utility by reason of its inertia, I employ a beam, 0, fixed to the shaft and balanced on said shaft by counter-weights f, which are adjustable on said beam, so .as to vary the leverage of said beam and consequently con- 0 trol the power proportionately with the desired or requisite expenditure. Thus the longer the leverage the greater the power or impetus, and hence, if the machinery to be driven be light, the leverage will be decreased by moving the counter-weights nearer the center or toward the shaft, and vice versa. This beam, being balanced, will stand either vertical or horizontal when the motor is at rest;

but I have purposely shown it in a false position in Fig. 1, so as to more plainly illustrate the construction of parts.

Pittman-rods g depend from the cranks c c of shaft 1), and are connected to levers h,which are pivoted at 1', in the same horizontal plane, to the frame-work A. These levers h are connected by vertical adjustable linksj with handlevers k, which last-named levers are also pivoted in the same horizontal plane to the framework, and also in the same vertical plane with the levers 71, so that said levers h andk are parallel; but the parallelism of the levers h and levers 70 may bedeparted from and the location of the pivots of the levers h changed so as to vary the center of motion, and hence their throw; and so, also, the links may have an adjustable connection with the levers h to effect the same end with respect to the levers k. The levers 7c are levers of the third order, and by giving them an u'p-and-down motion or vertical vibration on their fulcral pivots the motion is transmitted through the links and levers h to the pitman-rods and by them to the crank-shaft, to .which a rotary motion is imparted, and as soon as the equilibrium of the beam is disturbed and it is once set in motion it assist-s in the vibration of the levers, overcomes the weight of the parts, and thereafter becomes the controlling element'in the power.

A motor of this simple construction will be found very efficient in rural districts where horse-powers, steam-engines, and other powers are inaccessible or not available.

What I claim is- 1. A mechanical motor comprising the following elements, namely: a frame, A, the crank-shaft 11, mounted thereon, the balanced beam 6, secured to said shaft, pitmen g, engaging the cranks in said shaft and connected to levers h, which have their pivots on the frame, hand-levers 7c, and links j, connecting the said hand-levers and the levers it, all combined and arranged substantially as shown and described.

2. A mechanical motor consisting of the frame A, a crank-shaft, I), mounted thereupon, 9 5

a balancing device secured to said shaft, pit

men depending from the cranks ofsaid In testimony whereof Ihavehereunto set my shaft, levers 71/, pivoted at one end to the frame hand this 4th day of May, A. D. 1886. and connected at their other ends with the said pitmen, hand-levers k, and links 9', con- JAMES GREGORY. neeting said hand-1evers with the levers h between the ends of the latter, all constructed, \Vitnesses:

combined and arranged substantially as de- D. A. ToWNsEND,

It is hereby certified that in Letters Patent No. 361,937, granted April 26, 1887, u the application of James Gregory, of Bogansville South Carolina, for an improvemer Motors, errors appear in the printed specification requiring the following correcti to Wit: In the description of the figures of the drawing, page 1, line 19, the on side elevation should read perspective view, and in lines 20-1 the words plan vi should read sectional side elevation and that said Letters Patent should be read w these corrections therein that the same may conform to the record of the case in Patent Office.

Signed, countersigned, and sealed this 3d day of May, A. D. 1887.
